Cholera House / Casa del Cólera (Valparaíso)

The name 'Cholera House' (Spanish: Casa del Cólera) appears in the prompt as an abandoned residential building in Valparaíso associated with 'plague lore.' The supplied source materials do not contain any site-specific historical records, dates of construction, ownership information, municipal documentation, photographs, or local-news accounts verifying the existence, location, or condition of such a house in Valparaíso. No eyewitness testimony, folkloric narratives, or documented paranormal incidents tied to a Valparaíso Cholera House are present in the provided excerpts. The only materials available in the research set are a general medical overview of cholera (Wikipedia) and several historical Hong Kong newspaper excerpts that mention cholera in unrelated public-health contexts; these do not corroborate any claims about a Valparaíso house. Because of these gaps, all site-level details remain unverified in the supplied sources. Recommended next steps include consulting Chilean municipal archives, local Valparaíso newspapers and oral-history collections, heritage inventories, and cadastral records to establish whether a named Casa del Cólera existed and to collect any associated folklore or witness accounts.
